The second is to know the proper size of one’s bow so that he shoots with full awareness (1).
The third is to know the correct length of the string (2).
The fourth is to know the size of the fūq, the nocking point in which the string is set.
The fifth is to know the length of the arrow.
The sixth is to know the extent of his own strength (3).
The seventh concerns the postures of sitting and standing.
The eighth is to aim for accuracy, not for distance.
The ninth is effective penetration.

As for the two qualities by which archery is perfected—and they are its very essence—they are patience and God-fearingness. This is a truly excellent statement.

A group has said: the pillars of archery are four—speed, power, accuracy, and vigilance. The real archer is the one in whom these four are complete, and each of them depends on its sisters, just as archery itself depends on four things: the bow, the string, the arrow, and the archer.

If a man’s arrow struck the target but had no power to penetrate, it would produce no effect.
